Jason Thin-to-Thick Extra Volume Conditioner provides weightless manageability and volume to fine, thinning hair. Hair-strengthening panthenol and biotin help stimulate growth, while vitamins C and E nourish the entire hair shaft for improved volume with fewer fly-aways and split ends. The result is full, shiny hair with a boost of volume. Our conditioner is made with safe, gentler and effective ingredients and contains no parabens, sulfates, phthalates or petrolatum.
